I have a piece of property with 8 or 9 grapevines thought to be about 60 years old. They have to be moved within the next three weeks or be destroyed. My husband and I would love to have them at our house and we'd like to transplant them except for it's July. We've already cut one of them back and sap is just pouring out of it and we're afraid we've already killed it. Are we completely out of luck saving these guys or does someone have some ideas?
